Volvo is giving S60 buyers – courtesy of Polestar – a chance to juice up their S60s without going all the way to the R-Design model. Polestar is the tuner responsible for Volvo's STCC program and the firm has engineered an ECU reflash that boosts the S60's power numbers from 300 horsepower and 335 pound-feet of torque to 325 hp and 354 lb-ft.

Swedespeed was given a chance to test a pre-production version of the software and had it installed on their project S60 T6 AWD. The unofficial results were a 0.3-second drop in the 0-60 mile-per-hour time, getting the S60 within sight of the lighter, rear-wheel-drive BMW 335i and the heavier, all-wheel-drive Audi S4. Mid-range torque, though, appeared to be the big winner, with Swedespeed noting improved passing chops.

When it's officially offered, the upgrade is expected to cost around $1,500 or so, and be a quick install at the dealer. Fuel economy numbers aren't on the table yet, but Swedespeed will have more details of their time with the car soon. Follow the link for the full story.
